f :PLoWING-MACHINE.

To all whom z't may concern Y Be it known that LIIERMAN HORMAN, a citizen of the United States, and resident of the town of Arnold Mills, in the county of Providence and State of Rhode Island, have linvented. certain new andzuseful Improvements in PlowingsMachines, of which 4the following is a specification.

This invention relates to improvements in plowing machines, and has for its object'to provide a tractor carrying one or more plows, said tractor being providedl with Ameans'for imparting to the plows 'an intermittent plowing action and lto move them in a direction transversely to that of the travel of the tractor. y Y s IA furtherobject of the invention is to impart a longitudinal movement to the plows in addition to the circular movement, to increase the length of the' eective working stroke of the plow.'A s

It is found in practice in the use of tractors for plowing purposes that in order to drag a number Yofplows successfully the ftractor must be very heavy to provide suiiicient traction to prevent the wheels from slipping. To'obviate this diiculty, I have provided a plowing machine which works 'the plows transverselyv tothe travel of the paratively light inweight.

W'ithv these and other objects in `view,.the invention consists of certain novel features of construction, as willv bevmore fully described, and .particularly pointed 'out in the appended claims. A

In the accompanyingy drawings: Figure 1-is a plan view withk the guide frame :partly in section to better show the mechanism. Fig. 2`is an elevation sectioned on line 2 -2 of Fig.` 1. Fig. 3-.is a rear end S'pecicaton of Letters Patent.

"the forward axle 12 mounted on the steering wheels 13 land the rear axle 14 mounted'on Vthe driving wheels 15.` :The motor is pro- Avided with the usual driving shaft 16 which Arotates the driving wheels 15 through the worm 17 and worm gear'lS, the motor shaft then extending rearwardly to drive the plow operating mechanism hereinafter described.

tudinal Amotion. 'Fig fZ-is a plan' view `showing the diagonal form of cut which is vA plate '19 is slidably mounted on the plate 23 also bolted Yto the frame 10. On

this plate 19' is mounted three gearsf24, 25

, and 26, the middle gear 25 being mounted on the endfof driving shaft 27 while gears 24 I.and 26 are mounted on short shafts 28' and 29respectively. Gears 24 and 26, respec tively, vare provided with pins 30 and v31 projecting from their faces and offset Vfrom the center thereby serving as eccentrics or crank pins. A bar or beam 32.is connected to both Yof these pins, whereby the rotating of these gears impart to this bar a circular action. This bar thus mounted serves as a carrier for the plows any desired number of which may be mounted thereon. InFig. 3, I have shown two plows 33 rand 34 mounted on'this carrierjbar facing in one direction,and twoV plows 35 and 36 facing in the opposite direction but withdrawn from action, they, however, are pivotedly hung and so are arranged to be dropped kdown into operative position when called upon to act in a direction opposite to that of plows 33 and 34.

Another feature of my invention is that these gears with their plows and operating mechanism are all mounted on the sliding plate 19,7Which plate receives'a longitudinal motion through the medium of the connect-V Y ving rod 38, one end of which is connected to the crank pin 39V of the Vcrank 37 andthe `opposite end t0 the stationary pin4 40v in' theV wall 41 of the frame 22. This connecting` rod is provided with a central openirngy at f 42 so as toy straddle the driving shaftl 27` All this plate operating mechanism is driven from the main shaft 43` through the short vshafts 16 andv 2,7 `"and the knuckle joints 44 ende'l., which jeintspermit the lehgtudinal Y lateral movementfof the plate 19 during the driving action, the shaft 43 being telescoping er extendihle to. permit the lateral mremerltef the. elidehle plete 19.4

I have'shown the plowing i mechanismv as driven direct, from the main shaft'lV but in Ymany cases the speed of this portion of the shaft will be materiallylreduced bythe interposition of the usual power transmission gearing (not. herein ehewn),f Y

@Intlie operation of .my improved plowing Vmachine,V in Some instances the platev 19 which supportsv the gears, and the plow car-V rying bar 32, may beffixed, then when theseY gears' ere driven. threughtheehaft 2.7., the bar 32, which is journaled on the two crank pins 30. and 3l in these gears serves to. move the plows in a. circular direction and transversely to. the travel of the tractor. The

plows employed for my particular operation are preferably of these-called auger twist type and' are, set on an angle directed slightly forward as illustratediin Fig. l, wherebyV 'they will naturally take the combined lateral motion dueto the crank action, and; they forward motion due to. the movement of the Y. tatel and this `without dragging, formngf 45 a diagonal cut as illustrated ,by dotted lines c/.in Fig. 7 When the.. plows are operated byths. circular motion, the furrow formed willbe. sim-iler te. that illustrated in Fig; 5, Zi-Vi-ndicates, the cut of plow 33 and c indi` cat es the cut ofplow 34, the `width of the cutY corresponding toy twice the Y offset or throw of they crank.

In some instances it is found desirablel to make the furrow widerthan would naturally be madebyfthe swinging ofthe cranks alone,rtherefore, to. accomplishsthis, I havev Vmounted this plate,A 19. tol slide longitudinally in the pair of ways,this result` being accomplishedby providing.` another crank asV illustratedV at 37 in Fig. 4 and connecting the Slfme bythe rod 38 to a fixed Vpin 40 in the framewhereby the rotationl of thegear 24 by itsV driver 25, causes the plows to reciprocate and impart to. them a longitudinal motion as well asaicircular movement, by

By my improved method of operating the plowsy transversely to the travel ofthe tractor, I obtain the maximum effect of the ways resistance of the tractor to the action jof vthe plows, and also by an intermittent action of theeplows` I am enabled to utilize to the best,A advantage the, inertia Y of the tractor permitting itfto gain its speed and momentum during. Vthe intervals that. the plows are returning for4 anether operating stroke. Y Y' Having thus. Vdesemileed one. illustrative emhedmeet '0f my invention I desire' it. te bey understood that. any means. for operating one or morel plows inV adirection transverse .te the mevement Qt. the tractor, n the mm1- ner claimed will fallV Within the-` spirit and vscope of my inventiohj-V Y 'I'claimi"VV Y .Y l.
